Question

a bullet of mass 2g is having a charge 4uc the potential difference through which it should move to acquire a speed of 10m/s starting from rest​

Answer 1

Answer:

ma = mg a = g = 1 × 10 = 10m/s2 For crossing the bridge in minimum time, it has to travel with maximum acceleration u = 0, s = 500m, a = 10m/s2 s = ut + ½ at2 500 = 0 + (1/2) 10 t2

Explanation:
